Coating of NPK Fertiliser with Astarch-Based Biodegradable Polymer by Using a V-Star Reactor

Abstract

Mineral fertilisers such as nitrous, phosphorous and potassium (NPK –usually called macro elements) are one of the most significant products in agricultural industry. By providing nutrients to the plants, they play an important role in the process of regulating the acidity (pH) and the fertility of the soil and all it leads to increase the crops growth [6].

The Influence of Biopolymer Coated Fertilizer on the Agrochemical Parameters of the Soil

“…The PVA was modified by starch biopolymer solution by a method reported [2]. Polyvinyl alcohol was dissolved in water at 90 о C with continuous stirring for 40 min.…”

“…Additionally, the average annual growth is roughly about 6-7 %. High efficiency, ease of use and lowering costs for soil treatment allows to develop and maintain the biodegradable fertilizer market for long-term action [1][2][3]. The coating process (sulfur was used as a coat material) of the fertilizers was first developed in the United States in 1961, and commercial production began in 1978.…”
